Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a word processor that performs editing processing of Japanese and English texts using electronics technology such as digital memory and digital logic circuits.

The purpose of the present invention is to specify a certain area of a created text, and automatically convert full-width characters that can be converted to half-width characters or half-width characters that can be converted to full-width characters within the specified area. It converts the text into half-width and full-width characters, allowing you to create well-balanced and easy-to-read documents. An example of a commonly created sentence is shown in Figure 1A.
Each character area indicated by 100 represents a full-width character, and is a half-width character up to 1/2 of this full-width character.

In Figure 1, the text is made up of only full-width characters, and in this case, if the full-width letters and numbers are mixed in the kanji (full-width characters), the letters and numbers will be very long. It looks like it. Furthermore, the example shown in FIG. 1C is also created using only 100 full-width characters, and the numbers appear to be very elongated, similar to FIG. 1A.

For this reason, the examples in Figure 1 A and C above can be used as shown in Figure 1 B and D, if alphabetic characters and numbers mixed in kanji (full-width characters) are respectively displayed as half-width characters 101, the character string It becomes well-proportioned and easy to see. In other words, if you properly use full-width and half-width characters, the text will be easier to read. By the way, conventionally, when inputting characters, special operations such as setting a switch or the like to determine whether the characters to be input should be entered as half-width or full-width characters were used.

In addition, to convert a full-width character to a half-width character or a half-width character to a full-width character for a character string that has been input, move the cursor to the character to be converted one character at a time, and switch the half-width/full-width switch. It is necessary to set and correct the characters to be input, and the more characters that need to be converted, the more time-consuming the process becomes. In order to save time and effort when converting a character string once input, the present invention specifies an area and converts convertible characters within the area to full-width or half-width characters with a single touch.

This method is very effective because it shortens the time it takes for the operator to perform conversion processing, speeds up input operations, and reduces the operator's stress. The present invention will be explained in detail below with reference to an embodiment shown in the drawings.

First, FIG. 2 schematically shows the keys necessary to carry out the operations of the present invention.

Use the full keyboard to input 2001 characters, including kanji, numbers, alphabets, hiragana, katakana, and special symbols.

Reference numerals 201, 202, 203, and 204 are movement instruction keys for moving the cursor to a location where the area to be converted is specified, and the cursor is moved in the direction of the arrow of the key.

Reference numeral 205 is an area designation key for setting the position specified by cursor movement 201, 202, 203, and 204 as an area designation position.

Reference numeral 206 is an instruction key for converting half-width characters that can be converted into full-width characters in a designated area into full-width characters.

Reference numeral 207 is an instruction key for converting full-width characters that can be converted into half-width characters in a designated area into half-width characters.

Reference numeral 208 denotes function keys for executing various processes as a document processing device.

Next, FIGS. 3, 4, and 5 schematically illustrate the operation of the system of the present invention.

In FIG. 3, press the area designation key 205 at position 300, then move the cursor (movement designation keys 201, 2
02, 203, and 204) Then, when the area designation key 205 is pressed at position 301, it is determined from where to where the area to be converted is. FIG. 4 is a display state grave diagram showing that the set position is displayed in reverse to make it easier for the operator to understand the designated area.

After specifying the area as above, press the half-width conversion key
When 7 is pressed, full-width characters that can be converted to half-width characters within that area are converted to half-width characters, as shown in FIG. In FIG. 6, half-width convertible characters are the following underlined characters. Mountaintop Board 5th 07435-13-5521 Next, FIG. 6 is a diagram for explaining this conversion process in an easy-to-understand manner, and it is shown using the example sentences in FIG. 3 above.

600 is a text memory for memorizing characters input from the full keypad 200.

601 indicates the start address in the text memory 600 specified by the area specification key 205 (605
address) is pointer 1.

602 is an area specified by the area specification key 205;
It shows the last address in the text memory 600 (6
06 address) is a pointer.

603 is a register for reading data at the address indicated by pointer 1601.

A table memory 604 stores characters that can be converted into half-width (or full-width) characters.

The contents of this register 603 are compared with the character table memory 604 for characters that can be converted into half-width (or full-width) characters to check whether the characters are convertible. Furthermore, FIG. 7 shows the pointer 1601, pointer 0602, register 603, and
Convertible character table memory 604, text memory 600
2 is a flowchart showing the execution of this process using . The conversion process will be explained in detail below using this flowchart. First, as shown by 700, the first and last addresses specified in the area are set in pointer 1601 and pointer 0602, of which pointer 1
The character data in the text memory 600 at the address 601 is read into the register 603. Next, in step 701, the data is compared with the table memory 604 containing convertible characters to see if it can be converted.

At that time, if it matches a convertible character, 702 → 703,
Convert that character data and store the converted value in register 6.
03 is set in step 703, and if there is no match in step 702, the state moves directly to step 704. At step 704, the register 603 is written into the text memory 600 indicated by the pointer 1601. This completes the conversion of one character. Next, it is checked 705 whether the pointer 0602 containing the final address of the area specification matches the pointer 1601.

If there is a match here, it means that all areas have been completed. (EXIT) If there is no match in step 705, the pointer 1601 is incremented by 1 in step 706, then the data at that address is read again, and the process from step 700 is repeated. After performing the above processing, the conversion is completed as shown in FIG.

FIG. 8 is a block circuit diagram for executing the processing described so far, and this circuit will be explained.

800 is a full key for inputting character data.

801 is an area specification key, full-width conversion key, half-width conversion key,
These are function keys for executing processes such as

A circuit 802 controls the keyboards 800 and 801. Reference numeral 803 is a system control circuit that controls the entire system to perform this half-width/full-width conversion processing.

A text buffer 804 stores input character data.

A data buffer 805 reads and writes data to the text buffer 804 .

806 is an address circuit for the text buffer 804.

A register 807 is used when converting data read from the text buffer 804.

(corresponds to register 603 in FIG. 6).

Reference numeral 808 is a pointer 1 that stores the first address when an area is specified (corresponding to the pointer 1601 in FIG. 6).

Reference numeral 809 is a pointer that stores the final address when an area is designated (corresponding to pointer 0602 in FIG. 6).

A circuit 810 compares the pointer 1808 and the pointer 809 to check whether the conversion of the designated area is complete.

A convertible character table memory 811 stores convertible characters (corresponding to the memory 604 in FIG. 6).

812 is an address circuit of the memory 811, and 813 is a data buffer of the memory 811.

A comparison circuit 814 compares the data read from the text buffer 804 and stored in the register 807 with the convertible character table.

815 is a convertible character If so, convert it to the corresponding character data. and the circuit that sets it in register 807 be.

Next, the operation of this circuit will be explained.

First, the cursor is moved using the cursor movement instruction key among the function keys 801, and then the area specification key is pressed.

At this time, the keyboard control circuit 802 operates and a signal is output to the system control circuit 803. System control circuit 803
Now, when the area designation key is pressed, it operates to set the start address in the text buffer 804 to the pointer 1808 and the end address to the pointer 0809, respectively.

Next, when the half-width conversion key among the function keys 801 is pressed, the system control circuit 803 receives a signal from the keyboard control circuit 802, and first transfers the data in the text buffer 804 addressed by the pointer 1808 to the register 807. The address circuit 806 and register 807 of the text buffer 804 are controlled accordingly.
Next, the register 807 and the address circuit 812 and comparison circuit 814 of the convertible character table memory 811 are operated to check whether the data match.

If they match, a signal from the comparison circuit 814 is received, the conversion circuit 815 is activated, and the contents of the register 807 are converted. If they do not match, the conversion circuit is not operated. At the next timing, pointer 1808 and pointer 08
The comparison circuit 810 compares the address of 09.

If a match signal is received at that time, the system control circuit 80
3 completes a series of conversion processes. If a match signal is not received, the address of the pointer 1808 is counted up by 1 and the address circuit 80 of the text buffer 804
6 is activated, the next data is read into the register 807, and the same processing is repeated. The process is continued until the comparison circuit 810 detects a match, at which point the conversion process ends. In the above explanation, the conversion direction was indicated using two types of keys: the half-width conversion key and the full-width conversion key, but if the character at the cursor position is a full-width character, half-width conversion is automatically performed, and if it is a half-width character, full-width conversion is automatically performed. You can also do it like this.

Also, in this explanation, we mainly focused on individually specifying the beginning and end of an area as area specification, but for example, it is also possible to provide a page key, line key, etc. and convert the specified page, line, etc. can also be done easily. As described above, with the method of the present invention, it is very easy to convert a character string once input, so there is no need to worry about setting the switch to change to half-width or full-width characters when inputting. .

In addition, when converting half-width characters to full-width characters and vice versa, the specified area is converted at once, so there is no need to move the cursor to the characters to be converted one by one. Therefore, the processing time is shortened, the number of key touches is also reduced, and the operator's effort is greatly reduced, making it very effective.
